LibGDX - 在 Android 设备中找不到首选项位置
LibGDX - Cannot find Preferences location in Android Device
我正在使用 LibGDX 学习偏好。我可以在 Windows 和 Android 设备中成功地 运行 以下代码。文件 "MyDemo" 存储在
我的C:盘用户目录。它是完美的。我也可以 运行 Android 设备中的代码成功。但是,我找不到文件 "MyDemo"。空无一物
在 Android/data/...
package com.hkprogram.mydemo;
import com.badlogic.gdx.ApplicationListener;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.Preferences;
import com.badlogic.gdx.graphics.Color;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.graphics.g2d.BitmapFont;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;
public class MyDemo implements ApplicationListener {
private SpriteBatch batch;
private BitmapFont font1;
int screenWidth, screenHeight;
public Preferences prefs;
String name;
@Override
public void create() {
batch = new SpriteBatch();
font1 = new BitmapFont();
font1.setColor(Color.BLACK);
font1.setScale(5);
screenWidth=Gdx.graphics.getWidth();
screenHeight=Gdx.graphics.getHeight();
Preferences prefs = Gdx.app.getPreferences("MyDemo");
prefs.putString("Name", "Peter");
prefs.flush();
prefs = Gdx.app.getPreferences("MyDemo");
name=prefs.getString("Name","no name stored");
System.out.println("Name="+name);
}
@Override
public void dispose() {
}
@Override
public void pause() {
}
@Override
public void render() {
Gdx.gl.glClearColor(159/255.0f,220/255.0f,235/255.0f,0xff/255.0f);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
batch.begin();
font1.draw(batch, name, screenWidth/2, screenHeight/2);
batch.end();
}
@Override
public void resize(int arg0, int arg1) {
}
@Override
public void resume() {
}
}
您可以获得 MyDemo
执行此操作的路径:
File MyDemoFile = getDatabasePath("MyDemo.txt"); //choose your extension
if (MyDemoFile != null){
Log.d("Absolute path : ", MyDemoFile.getAbsolutePath());
}
